[0016] The above technical solution facilitates forming a stable support effect on the interior of the box body through the provided support ring and the reinforcing rib plate, thereby improving the compression and deformation resistance of the box body when pre-buried.

[0017] Furthermore, threaded holes adapted for bolts are provided on the front faces of the mounting posts and the baffle, and the four mounting posts are located on the inner side of the support ring and in contact with the inner wall thereof.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 2 In this embodiment, a welded steel pipe into the box, a household-free accessory for the box, includes a box body 1, a wiring mechanism 2 arranged on the box body 1, a baffle 3 installed on the front of the box body 1 and a support mechanism 4 arranged inside the box body 1. Four mounting holes 5 are opened on the outer peripheral wall of the box body 1. A plurality of mounting holes 5 are opened on the outer peripheral wall of the box body 1 for passing wires. The mounting holes 5 are sealed by the wiring mechanism 2, which can avoid the inconvenience caused by cement mortar entering the box body 1 when pre-buried the box body 1. When wiring, no burrs will be left inside the mounting holes 5, thereby avoiding the burrs scratching the wires when passing the wires, leaving safety hazards, providing convenience for efficient and safe construction, better practicality, and more convenient for promotion and use.

[0033] See also Figures 1 to 2The wiring mechanism 2 includes three disassembly plates 201 arranged on the outer peripheral wall of the box body 1, a sealing ring 202 fixed on the side of the disassembly plate 201 facing the box body 1, multiple reset plates 203 fixed on the side of the disassembly plate 201 facing the box body 1, a limit block 204 fixed on the side of the reset plate 203 facing the inner wall of the mounting hole 5, and a wire protection component arranged inside the bottom mounting hole 5. The reset plate 203 is a plastic elastic sheet with elastic deformation ability, and the limit block 204 is a trapezoidal block. The side of the limit block 204 facing the disassembly plate 201 contacts the inner wall of the box body 1, and the disassembly plate 201 is opposite to the mounting hole 5. When in use, determine the direction of the box body 1 where wiring is required, then push the limit block 204 in that direction relatively to cause the reset plate 203 to bend and produce elastic deformation, and further push the reset plate 203 to the side away from the box body 1, so that the disassembly plate 201 can be removed from the box body 1 without leaving burrs inside the mounting hole 5 and without damaging the mounting hole 5. The undisassembled disassembly plate 201 cooperates with the sealing ring 202 to seal the mounting hole 5 in that direction to prevent cement mortar from flowing into the box body 1 from the mounting hole 5 on that side. The disassembled disassembly plate 201 can also be recycled to reduce waste of resources.

[0034] See also Figures 1 to 2 In this embodiment, the wire protection assembly includes a connecting tube 205 that is slidably connected to the inside of the bottom mounting hole 5, a limiting ring 206 fixed on the outer peripheral wall of the connecting tube 205, a sealing ring 207 fixed to the bottom surface of the limiting ring 206, a threaded ring 208 threadedly connected to the outer peripheral wall of the connecting tube 205, and a wire protection tube 209 fixed to the bottom end of the connecting tube 205. A spiral groove that is adapted to the threaded ring 208 is opened on the outer peripheral wall of the connecting tube 205. The threaded ring 208 is arranged on the outside of the box body 1, the limiting ring 206 is arranged on the inside of the box body 1, and the inner of the connecting tube 205 is fixed to the bottom of the box body 1. There is a circular chamfer near the top of the wall. After the disassembly plate 201 is disassembled, take out the spare connecting pipe 205 and pass it through the mounting hole 5 from the inside of the box body 1 to the outside, so that the limiting ring 206 contacts the inner wall of the box body 1. Further, pass the threaded ring 208 from the end of the connecting pipe 205 located outside the box body 1 and rotate it, so that the threaded ring 208 abuts against the outer wall of the box body 1 and cooperates with the limiting ring 206 and the sealing ring 207 to perform a sealed connection. At this time, the wire protection pipe 209 that needs to be embedded in advance can be welded to the end of the connecting pipe 205 located outside the box body 1.

[0035] See also Figures 3 and 4In this embodiment, the support mechanism 4 includes a support ring 401 fixed to the back of the baffle 3 and four reinforcing ribs 402 fixed between the inner walls of the support ring 401. A U-shaped groove 403 is provided on the outer peripheral wall of the support ring 401. The support ring 401 is a rectangular ring. The outer peripheral wall of the support ring 401 contacts the inner peripheral wall of the box body 1 and the two are slidably connected. The four reinforcing ribs 402 are cross-fixed in a criss-cross shape. When the box body 1 is embedded in the pre-embedded box body 1, the baffle 3 seals the front of the box body 1 to prevent cement mortar from flowing into the front of the box body 1. At the same time, the support ring 401 on the back of the baffle 3 is inserted into the inside of the box body 1 and abuts against its inner wall. Cooperating with the reinforcing ribs 402 can effectively improve the compressive resistance of the outer peripheral wall of the box body 1, and prevent the outer peripheral wall of the box body 1 from sinking and deforming inward when embedded.

[0036] See also Figures 2 to 3 In this embodiment, four mounting posts 6 are fixed on the inner wall of the rear side of the box body 1, and four bolts 7 that penetrate the baffle 3 and are respectively threadedly connected to the four mounting posts 6 are threaded on the front of the baffle 3. Threaded holes that are adapted to the bolts 7 are opened on the front of the mounting posts 6 and the front of the baffle 3. The four mounting posts 6 are all located on the inner side of the support ring 401 and in contact with its inner wall. When the pre-buried construction of the box body 1 is completed and the switch socket panel needs to be installed, the four bolts 7 are unscrewed to separate them from the mounting posts 6 to remove the baffle 3. At the same time, the support ring 401 and the reinforcing rib plate 402 are taken away from the box body 1, and the wiring operation can be carried out and the switch socket panel can be installed. When the baffle 3 is removed, the mounting posts 6 can also be used to install the switch socket panel.

[0037] The working principle of the above embodiment is:

[0038] (1) When in use, determine the direction of the box body 1 where the wiring is required, then push the limit block 204 at that direction relatively to bend the reset plate 203 to produce elastic deformation, and further push the reset plate 203 to the side away from the box body 1, so that the disassembly plate 201 can be removed from the box body 1 without leaving burrs inside the mounting hole 5 and without damaging the mounting hole 5. The undisassembled disassembly plate 201 cooperates with the sealing ring 202 to seal the mounting hole 5 at that direction to prevent cement mortar from flowing into the box from the mounting hole 5 on that side. After disassembling the body 1 and the disassembly plate 201, take out the spare connecting tube 205 and pass it through the mounting hole 5 from the inside of the box body 1 to the outside, so that the limiting ring 206 contacts the inner wall of the box body 1. Further, pass the threaded ring 208 from the end of the connecting tube 205 located outside the box body 1 and rotate it so that the threaded ring 208 abuts against the outer wall of the box body 1 and cooperates with the limiting ring 206 and the sealing ring 207 to form a sealed connection. At this time, the wire protection tube 209 that needs to be embedded in advance can be welded to the end of the connecting tube 205 located outside the box body 1;

[0039] (2) When pre-embedding the box body 1, the baffle 3 seals the front of the box body 1 to prevent cement mortar from flowing in from the front of the box body 1. At the same time, the support ring 401 on the back of the baffle 3 is inserted into the inside of the box body 1 and abuts against its inner wall. In conjunction with the four mounting columns 6 and the reinforcing rib plate 402, the compressive strength of the outer wall of the box body 1 can be effectively improved to prevent the outer wall of the box body 1 from being dented and deformed inward during pre-embedding. When the pre-embedding construction of the box body 1 is completed and the switch socket panel needs to be installed, the four bolts 7 can be unscrewed to remove the baffle 3, and the support ring 401 and the reinforcing rib plate 402 can be taken away from the box body 1. Then, wiring operations can be carried out and the switch socket panel can be installed.
